2019-2020年人教版高中英語必修三教學(xué)案：Unit 4 Section 4(含答案) [原文呈現(xiàn)][讀文清障] A VISIT TO① THE MOON Last month I was lucky enough to have a chance to② make a trip③ into space with my friend Li Yanping, an astronomer. We visited the moon in our spaceship④！ Before we left, Li Yanping explained to me⑤ that the force of gravity⑥ would change three times on our journey and that the first change would be the most powerful. Then we were off⑦. As the rocket rose into the air, we were pushed back into⑧ our seats because we were trying to escape the pull⑨ of the earths gravity. It was so hard that we could not say anything to each other⑩. Gradually? the weight lessened? and I was able to talk to him. “Why is the spaceship not falling back to? the earth? On the earth if I fall from a tree I will fall to the ground.” I asked.“We are too far from? the earth now to feel its pull，” he explained, “so we feel as if there is no gravity at all. When we get closer to? the moon, we shall feel its gravity pulling? us, but it will not be as strong a pull as? the earths.” I cheered up? immediately and floated?weightlessly? around in our spaceship cabinwatching the earth bee smaller and the moon larger. ①名詞visit后接to，意為“到……的旅行”，to為介詞。 ②have a chance to do sth.有機會做某事 ③make a trip(＝take a trip＝go on a trip)去旅行 ④in our spaceship乘宇宙飛船，相當于by spaceship。 spaceship/speIs?Ip/n.宇宙飛船 ⑤explain sth. to sb.“向某人解釋某事”。本句中explain的賓語是兩個that從句，因太長而后移了。 explain后不能直接跟sb.，須先接介詞to。類似的詞還有say, announce等。 ⑥the force of gravity地心引力 ⑦be off離開，起飛。在本句中相當于take off。 ⑧push ...back into ...把……推回到…… ⑨pull/p?l/n.&vt.拉(力)；拖；牽引力 pull down拆毀 pull on/off匆忙穿上/匆忙脫掉 ⑩so ...that ...如此……以至于……，引導(dǎo)結(jié)果狀語從句。 ?gradually adv.逐漸地；逐步地，漸漸地 ?lessen/lesn/vi.&vt.減少；減輕 ?fall back to 落回到 ?be far from離……很遠 ?get close to接近，靠近 ?feel sb./sth.doing sth.感到某人/某物在做某事 ?as strong a pull as為“as＋adj.＋a(n)＋n.＋as”結(jié)構(gòu)。 ?cheer up感到高興；感到振奮 ?float/fl??t/vi.&vt.(使)浮動；(使)漂浮n.漂浮物 ?weightlessly/weItlIslI/adv.失重地 cabin/kbIn/n.小屋；船艙 現(xiàn)在分詞短語watching the earth bee smaller and the moon larger作伴隨狀語。watch sb./sth. do sth.觀察某人/某物做某事。 月球之旅 [第1～2段譯文] 我的朋友李彥平是一位天文學(xué)家，上個月我非常有幸有機會同他一起去太空旅行。我們乘宇宙飛船游覽了月球！ 在起程以前，李彥平向我解釋說，在我們的旅行中會有三次引力的改變，而第一次的改變將是最強的。隨后我們就起航了。隨著火箭升入太空，由于我們在努力掙脫地球的引力，我們被向后推在座位上。這種引力太強了，以至于我們彼此間都不能說話了。漸漸地，這個力量慢慢減小，我才能夠同他講話。我問道：“為什么宇宙飛船不會落回到地球呢？在地球上的時候，如果我從樹上掉下來，總會朝地上落下去的?！崩顝┢浇忉屨f：“現(xiàn)在我們離地球太遠了，感覺不到地球的拉力，所以我們感覺好像完全沒有地球引力了。當我們更接近月球時，就會感到月球的引力在拉我們。但是月球的引力不像地球的引力那么大。”我立刻感到很高興，由于失重我在太空艙里飄來飄去，我望著(身后的)地球越來越小，而(前方的)月球越來越大。 When we got there, I wanted to explore immediately. “e on，” I said. “If you are right, my weight will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less！” I laughed and climbed down the steps from the spaceship. But when I tried to step forward， I found I was carried twice as far as on the earth and fell over. “Oh dear，” I cried, “walking does need a bit of practicenow that gravity has changed.” After a while I got the hang of it and we began to enjoy ourselves. Leaving the moons gravity was not as painful as leaving the earths. But returning to the earth was very frightening.We watched, amazed as fire broke out on the outside of the spaceship as the earths gravity increased. Again we were pushed hard into our seats as we came back to land. “That was very exhausting but very exciting too，” I said. “Now I know much more about gravity! Do you think we could visit some stars next time？”“Of course，” he smiled, “which star would you like to go to？” e on快點兒。常用于祈使句中以鼓勵某人，意為“動手吧；快點兒；加油”。 step forward朝前走；邁步向前 twice as far as“……的兩倍遠”。倍數(shù)表示法：倍數(shù)(twice, three times ...)＋as＋adj./adv.＋as。 fall over跌倒；摔倒 動名詞walking在此處作主語。does為助動詞，加強語氣，意為“確實”，其后跟動詞原形。 now that既然(引導(dǎo)原因狀語從句) get the hang of 熟悉；掌握；理解 enjoy oneself盡情地玩；玩得高興 break out 突發(fā)：爆發(fā) exhaust/Iɡz??st/vt.用盡；耗盡；使精疲力盡 exhausting adj.令人精疲力盡的 exhausted adj.感到精疲力盡的 exhaustion n．精疲力盡；用光，耗盡 know在此處相當于understand，意為“理解，明白”?！? [第3～4段譯文] 我們到達月球時，我就想立即進行探測?！皝戆桑蔽艺f，“要是你講得對，我的重量就會比在地球上小，因為月球更小，而我就能更自由地活動了。如果我在月球上待的時間足夠長的話，我甚至可能長得更高，我的體重肯定也會變得更輕！”我笑著從宇宙飛船的梯級上爬下來。但當我試圖往前走時，我發(fā)現(xiàn)自己被帶到一個步幅相當于地球上兩倍遠的地方并且摔倒了。“天哪，”我大聲說，“重力改變了，看來走路的確需要練一練了?！边^了一會兒，我才掌握了走路的訣竅，我們這才開始感到自如了。 擺脫月球引力不像擺脫地球引力那樣痛苦。但是返回到地球的經(jīng)歷卻是非常嚇人的。我們驚奇地看著，隨著地球引力的增加，宇宙飛船的外層燃燒起火。當我們回到地面時，我們又(感到)被重重地推回在座位上。我說道：“真是精疲力盡了，但也很激動人心。關(guān)于引力，我現(xiàn)在就懂得更多了！你認為下次我們可以去別的星球上游覽嗎？”“當然可以，”他笑著說，“你想到哪顆星球上去呢？” Step 1　True (T) or False (F)． 1．The spaceship cant fall back to the earth because it is too far away from the earth.(　　) 2．When I was on the moon I felt I was heavier than I am on the earth.(　　) 3．At the very beginning，the author felt strongest of the gravity of the earth.(　　) 答案：1.T　2.F　3.T Step 2　Read the text and choose the best answers. 1．The passage mainly talks about________.

For example, the information for weather forecasts is sent by satellite. Some satellites have cameras which take photographs of the Earth to show how clouds are moving. Satellites are also used to connect our international phone calls. puter connections of the World Wide Web and Internet also use satellites. Many of our TV programmes e to US through satellites. Airplane pilots also sometimes use a satellite to help them find their exact location. We use satellites to send television pictures from one part of the world to another. They are usually 35,880 kilometres above the equator (赤道). Sometimes we can see a satellite in the sky and it seems to stay in the same place. This is because it is moving around the world at 11,000 kilometres an hour — exactly the same speed that the earth rotates (轉(zhuǎn)動). A satellite must orbit the Earth with its antennae (天線) facing the earth. Sometimes, it moves away from its orbit, so there are little rockets on it which are used to put the satellite back in the right position. This usually happens about every five or six days. Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth. A satellite usually works for about 10～12 years. Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to the Earth to be repaired. Often, very old or broken satellites are left in space to orbit the Earth for a very long time. This is very serious because some satellites use nuclear power and they can crash into each other. 語篇解讀：本文是一篇科普說明文。文章對各種衛(wèi)星的用途、衛(wèi)星工作的狀態(tài)以及人們對已損壞衛(wèi)星的處理辦法進行了解釋說明。 1．Which of the following is NOT done by satellites according to the passage? A．Sending information for weather forecasts. B．Taking photographs of the Earth. C．Sending TV pictures. D．Providing food for airplane pilots. 解析：選D　細節(jié)理解題。根據(jù)第一段和第三段首句不難看出，衛(wèi)星可以傳遞天氣預(yù)報信息、拍攝地球照片、傳遞電視圖片等，但是沒說為飛行員提供食物，所以選擇D項。 2．Why does the satellite move around the world at the same speed as the Earth rotates? A．In order to take photographs. B．In order to stay in a certain position in the orbit. C．In order to move away from its orbit. D．In order to send television pictures. 解析：選B　細節(jié)理解題。根據(jù)第三段內(nèi)容可以看出，衛(wèi)星之所以用和地球自轉(zhuǎn)相同的速度繞地球旋轉(zhuǎn)，是為了保持在一定位置上。顯然B項正確。 3．What does the underlined word “This” in the 3rd paragraph refer to? A．A satellite. B．A little rocket. C．A satellite seems to stay in the same place in the sky. D．The satellite puts the rockets in the right position. 解析：選C　代詞指代題。this在此替代前文的“Sometimes we can see a satellite in the sky and it seems to stay in the same place.”故選C項。 4．Which is true of satellites? A．A satellite usually works for about 10～12 years. B．Every time a satellite gets broken, it is brought back to the Earth to be repaired. C．A broken satellite is never left in space. D．Broken satellites often crash into each other. 解析：選A　細節(jié)理解題。根據(jù)最后一段不難看出A項正確。 Ⅱ.語法填空 Friendship is one of the most important things in everyones life. __1__ is very difficult to find a better definition (定義) of friendship.
